A coronary stent may be lost in the peripheral or visceral arterial system with an incidence ranging from 0.9 to 8.4%, however, a limb or organ ischemia after stent migration is very uncommon. We report the case of an 83-year-old man who underwent coronary artery stenting at our Hospital's Cardiological Department. During this difficult procedure, due to the critical stenosis of the circumflex ...

Background: For coronary to pulmonary artery fistulas, operations are often indicated by the existence of myocardial ischemia or aneurysmal formations. Because lesions do not form in identical ways, a variety of surgical procedures are performed. We propose standardizing this operation for a safer and more reliable outcome. Methods: We evaluated 8 cases of operations for coronary to pulmonary a...

OBJECT To enhance the surgeon's dexterity and maneuverability in the deep surgical field, the authors developed a master-slave microsurgical robotic system. This concept and the results of preliminary experiments are reported in this paper. METHODS The system has a master control unit, which conveys motion commands in six degrees of freedom (X, Y, and Z directions; rotation; tip flexion; and ...

With the introduction of percutaneous arterial access by Seldinger in 1953, the need for surgical arteriotomy was eliminated.1 However, potential trauma to the artery from needle puncture, the introduction of multiple catheters, and the process of closure was recognized early and has, to some degree, remained unresolved for 60 years. Manual compression is generally effective for closure, but it...

OBJECTIVE Haemodynamic stress has been considered to be an important factor in aneurysm formation and growth. The aim of this study was to reveal the effect of salt induced hypertension on the experimental saccular aneurysm model MATERIALS AND METHODS Forty Sprague-Dawley rats of both sexes in equal number were used in this study. Under general anesthesia with ketamine hydrochloride (Ketalar, P...

OBJECTIVES In-stent restenosis (ISR) remains a major complication of percutaneous coronary intervention, even in the current era of drug-eluting stents (DESs). We reviewed the clinical and angiographic outcomes of coronary endarterectomy with stent removal using an off-pump technique in patients with ISR in the left anterior descending artery (LAD). METHODS Twelve patients with long-segment I...

OBJECTIVE To report our initial experience on the technical feasibility and safety for hemostasis of a new pneumatic compression device in patients undergoing femoral arteriotomy. MATERIALS AND METHODS This study included 40 consecutive patients in whom hemostasis after transfemoral catheterization was readered by using a pneumatic compression device consisting of an inflatable bulb-containin...

OBJECTIVES The authors sought to study the safety and efficacy of the MANTA Vascular Closure Device (VCD), a novel collagen-based technology dedicated to closure of large-bore arteriotomies. BACKGROUND Novel transfemoral therapeutic interventions requiring large-bore catheters have become valid minimally invasive options but have inherent access management challenges. To date, no dedicated va...

UNLABELLED Between May 1974 and December 1993, 37 patients (0.75%) with a double-chambered right ventricle underwent surgical repair. The patients ranged in age from 11 months to 12 years (mean 4 +/- 1.1 years). Cardiac catheterization was performed in 36 patients. The proximal right chamber pressure was 118 +/- 10 mmHg and the mean ventricular gradient pressure was 75 +/- 10 mmHg. A ventricula...

Abstract Background The access site vascular complications remain a relevant complication following transcatheter aortic valve implantation (TAVI). They are frequently associated with closure device failure (VCD). Incidence of depends on different factors such as patient's characteristics and clinical risk profile, femoral morphology, sheath size or technical procedural experience. Their rate i...
